Description: About 1.5 sec after the scanner drive signal output, the BDI* signal is not detected 3 times or more for 1.0 sec. While the laser is ON, the BD signal cycle is not as indicated for 0.5 or more continuously.
Causes: - The laser driver/BD PCB is faulty (laser activation failure, BD detection fault). The DC controller PCB is faulty. The image processor PCB is faulty.
Remedy: 1. Wiring Is the wiring from the DC controller PCB to the laser scanner unit normal? NO: Correct the wiring 2. Laser scanner unit Try replacing the laser scanner unit. Is the problem corrected? YES: End. 3. DC controller PCB, Image processor PCB Try replacing the DC controller PCB. Is the problem corrected? YES: End. NO: Replace the image processor PCB.
Code: E110
Description: The scanner fails to reach the target speed of rotation 10 sec after the laser scanner motor reaches constant speed state.
Causes: - The laser scanner motor is faulty. The DC controller PCB is faulty.
Remedy: 1. Laser scanner unit, DC controller PCB Try replacing the laser scanner unit. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.
Code: E805
Description: While the fan is rotating, fan lock state is detected for 10 sec or more continuously.
Causes: - The fan is faulty. The DC controller PCB is faulty. The image processor PCB is faulty.
Remedy: 1. Foreign matter Is there any foreign matter that hinders the rotation of the heat discharge fan? YES: Remove the foreign matter. 2. Wiring, Connection Are the wiring and connection (connectors) of the fan normal? NO: Correct them. 3. Fan Try replacing the fan. Is the problem corrected? YES: End. 4. DC controller PCB/Image processors PCB Try replacing the DC controller PCB. Is the problem corrected? YES: End. NO: Replace the image processor PCB.
Code: E810
Description: The case that the toner bottle is detected, but not the cartridge.
Causes: - The DC controller PCB is faulty. The cartridge is faulty.
Remedy: 1. High-voltage contact (between machine and the developing unit) Is the high-voltage spring used to supply high voltage to the developing unit soild? YES: Clean it. 2. High-voltage contact (between high-voltage spring and DC controller PCB; J207) Is the connection between the high-voltage spring and the DC controller PCB(J207) normal? NO: Correct the connection. If the problem cannot be corrected, replace the faulty part. 3. Developing unit, DC controller PCB Replace the developing unit. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.
